Its compact 2.5mm pitch size and 3A rating current capacity render the JST SM connector ideal for efficient power delivery in modular LED lighting systems. Taking Philips Hue smart bulb as an example, its PCB board level interconnection scheme with jst sm connector lowers the drive circuit volume by 32%, enhances the power conversion efficiency to 93% under 120V/60Hz conditions, and lowers the yearly power consumption of an individual lamp from 9.8kWh to 6.5kWh. The gold-plated contact of the connector (0.15μm thickness) still maintains the contact resistance ≤10mΩ under 85℃ high temperature environment, being applied to the Osram plant factory LED array successfully, so that 2000 hours continuous operation light decay rate is within 3%, and the performance attenuation is 50% less than the conventional connector.
In the outdoor LED display market, jst sm’s IP67 protection level and -40 ° C to 105 ° C temperature range tolerance significantly improve reliability. In the 5000㎡ floor tile screen project of the Beijing Winter Olympics developed by Zhouming Technology, under the extremely cold weather of -25℃, the signal transmission module used along with the connector has maintained the bit error rate of data transmission below 10⁻ and the refresh rate has been maintained with an accuracy of 3840Hz±2%. Its two-row 24-pin structure enables synchronous transmission of power supplies and PWM dimming signals, which helps Rayman Opto-Electronics to enhance the COB display gray level from 16bit to 22bit and the color restoration accuracy ΔE≤1.2, meeting film and television level color requirements. According to statistics, the breakdown rate of LED advertisement displays using this program has been reduced from the industry average of 0.8 times/thousand hours to 0.15 times/thousand hours, and the operation and maintenance cost has been reduced by 42%.
For car LED light systems, jst sm’s vibration resistance (20-2000Hz, 50G acceleration) ensures crucial connection stability. The connector was used in Tesla Model 3’s through-through taillights for 5000 insertion and uninsertion zero failure rate under SAE J2380 wet thermal cycle test (85 ° C /85%RH). Its 0.6N·m locking force enables the BMW iX matrix headlamp to keep the optical axis offset within ±0.05° in the 40m/s wind speed wind tunnel test, meeting the requirements of ECE R112. The ambient light system in NIO ET5 accomplishes the cascade of 256-color LED modules through jst sm, shortens the transmission delay of the signal from 3.2ms to 0.8ms, and enhances the dynamic light response speed by 300%.
In smart lighting control, the jst sm connector transmits the data of DALI-2 protocol, and the ultra-thin 3.5mm height design reduces the thickness of OpP Lighting’s embedded downlight to 28mm. The connector achieves a 50ms level response of networking in Doodle Smart’s Zigbee 3.0 dimmer module and reduces the failure rate of firmware upgrade of smart lamps from 1.2% to 0.3%. According to TrendForce statistics, in 2023, 36% of the world’s LiFi visible light communication equipment adopts the jst sm solution, and the supported 10MHz bandwidth allows the positioning system accuracy of Shenzhen Metro Line 11 to reach ±15cm, 5 times the conventional RF technology.
In terms of cost control, jst sm’s automated crimping terminal design improves the efficiency of installation by 60%, reducing the production line beat of LED panel lights from 45 seconds per piece to 28 seconds per piece in the lighting Wuhan factory. It is compatible with AWG 30-22 wire gauge, thus increasing the wiring density of Sanan’s Mini LED backlight module to 38 lines /cm² and reducing the material cost by 19%. It is written in the Dell’Oro Group report that the 5G smart street light project ROI with the connector is lowered to 2.3 years, 40% faster than the traditional scheme, propelling the global LED connector market size to surpass $2.7B by 2025, with a jst sm technology contribution rate of 31%.
